Used in a variety of different processes of a vacuum system, a wide range is divided into two categories. First, a dynamic vacuum system, which relies on the continuous operation of vacuum apparatus, the exhaust gas continuously into the system to obtain a stable vacuum. The gas flows within the system, the entire pressure vary. The second is a static vacuum system. It has nothing to with the outside world through the point, after the establishment of the vacuum pump can not be maintained for a long time, the system pressure is equal everywhere .

Vacuum pump is the heart of the system, the industry generally use mechanical pumps, booster pumps and diffusion pumps.

Mechanical pumps include rotary vane vacuum pumps, fixed vane pump, rotary piston pump, water ring vacuum pumps, screw pumps, etc., can be used alone as a main pump low vacuum system can also be used as pre-high vacuum pump system.

Diffusion pump working pressure 1.3x10-1 ~ 6.7x104Pa (no cold trap) and 1.3x10-5 ~ 1.3x10-7Pa (cold trap) As can be used as the main pump high vacuum systems. Runtime must be equipped with front pump. Mechanical pump 1pa following poor performance. In order to better fit with the diffusion pump, between the mechanical pump and diffusion pump booster pump can be set. You can choose Roots booster pump and booster pump oil and so on. For ultra-high and high vacuum system, there are molecular pumps, suction pump, Chin pumps and cryogenic pumps and other options.

What is the vacuum
Vacuum means that a given gas pressure within the space of less than the area of a standard atmospheric pressure gas state.
Vacuum is rarefied gas environment. Compared with the atmosphere it has a number of advantages, such as gas thin, less oxygen, clean environment...

Vacuum pump in a variety of different job categories effect have?
Vacuum pumps work in a variety of different play areas in effect summed up in the following areas:
1, main pump: the so-called main pump is a vacuum system is evacuated container is directly evacuated to the vacuum pump ...
